G&P M4 hopup problem.

[tiger-unit]

Hey, my gun is shooting, but there is NO hopup, I have sdjusted the hopup, and no difference, so am I gonna have to buy a new hop up sytem, or is htis fixable ?

[Kid]

just in case, what range are you shooting at? basement size or outdoor?

[ILLusion]

if it's at distance and still no hop up effect, might want to take the unit apart to see if the little bucking is still there.

also, if you've recently applied any lube to your hop up unit or inner barrel, the oil may be preventing the hop up rubber from getting any good friction on the BB to impart a good spin.

I have taken the gun in half, and I noticed that the peice that clips on to the hopup and innner barrel(dont know what its called), but its broken, its just not wuite crackenough to completely snap in half, but I can just rest it into the little slit, could that be causing the problem ?

Could be, if your gun is new, contact G&P theyre pretty good at sending warranty replacement parts like that through the mail.
